CY7C1442AV33  
CY7C1446AV33  
PRELIMINARY  
36-Mbit (1M x 36/2M x 18/512K x 72)  
Pipelined Sync SRAM  
Features  
Functional Description[1]  
• Supports bus operation up to 250 MHz  
The CY7C1440AV33/CY7C1442AV33/CY7C1446AV33 SRAM  
integrates 1,048,576 x 36, 2,097,152 x 18 and 524,288 x 72  
SRAM cells with advanced synchronous peripheral circuitry  
• Available speed grades are 250, 200,167 MHz  
• Registered inputs and outputs for pipelined operation  
• 3.3V core power supply  
and a two-bit counter for internal burst operation. All  
synchronous inputs are gated by registers controlled by a  
positive-edge-triggered Clock Input (CLK). The synchronous  
inputs include all addresses, all data inputs, address-pipelining  
Chip Enable (CE1), depth-expansion Chip Enables (CE2 and  
CE3[2]), Burst Control inputs (ADSC, ADSP, and ADV), Write  
Enables (BWX and BWE), and Global Write (GW).  
Asynchronous inputs include the Output Enable (OE) and the  
ZZ pin.  
• 2.5V/3.3V I/O operation  
• Fast clock-to-output times  
— 2.6 ns (for 250-MHz device)  
— 3.2 ns (for 200-MHz device)  
— 3.4 ns (for 167-MHz device)  
Addresses and chip enables are registered at rising edge of  
clock when either Address Strobe Processor (ADSP) or  
Address Strobe Controller (ADSC) are active. Subsequent  
burst addresses can be internally generated as controlled by  
the Advance pin (ADV).  
• Provide high-performance 3-1-1-1 access rate  
• User-selectable burst counter supporting Intel®  
Pentium® interleaved or linear burst sequences  
• Separate processor and controller address strobes  
• Synchronous self-timed writes  
Address, data inputs, and write controls are registered on-chip  
to initiate a self-timed Write cycle.This part supports Byte Write  
operations (see Pin Descriptions and Truth Table for further  
details). Write cycles can be one to two or four bytes wide as  
controlled by the byte write control inputs. GW when active  
• Asynchronous output enable  
• Single Cycle Chip Deselect  
• Offered in JEDEC-standard 100-pin TQFP, 165-Ball  
fBGA and 209-Ball fBGA packages  
causes all bytes to be written.  
LOW  
The  
CY7C1440AV33/CY7C1442AV33/CY7C1446AV33  
• Also available in lead-free packages  
• IEEE 1149.1 JTAG-Compatible Boundary Scan  
• “ZZ” Sleep Mode Option  
operates from a +3.3V core power supply while all outputs may  
operate with either a +2.5 or +3.3V supply. All inputs and  
outputs are JEDEC-standard JESD8-5-compatible.
